Recent Reports About 214-214-5xxx Numbers

This number started calling Jan.15th, l6th, 17th and last call was on 1/23rd. I picked up the call on the 17th. A female's voice came on and she asked for my husband by name only, never asking me to identify who I was or giving out any reason for her call, but wanted to know if he was home, or if he is still living there or whether he had already moved. I did not provide her with any information but I kept repeating, "who is calling please". That angered her and she became belligerent & said that she would call when someone else answers and angrily hung up. Next time this person called, there was dead silence on the other line. My husband is very puzzled also.
